Hi,
When I run a spawn program over rsh/ssh, I notice that each time the
child program gets spawned, it will need to establish a new rsh/ssh
connection to the remote node to launch orted on that node, even the
parent executable and the orted are running on that node.
So I wonder if there is any
Hi Pak
I'm afraid I don't fully understand your question, so forgive me if I
don't seem to address the problem adequately. As I understand it, you
are asking about the scenario where someone wants to execute multiple
calls of mpirun, with the applications executing on the same set of
nodes. Y

First, the fact that an orted already exists on a node is not
sufficient to allow us to use it again for another application. The
orted must be persistent or else we do not allow a new application to
re-use it. This is required because the existing orted will go away

Hmmm...no, it appears that we are not talking about the same problem at
all. An internal comm_spawn is not at all equivalent to an external
execution of another mpirun command - even though the same functions
may get called, there is a very large fundamental difference between
the two scenarios
okay, sorry that I might have confused you before, but at least we are
all clear about the issues. It now sounds like I'll have to try
restricting the number of times the "qrsh" gets called in the sge pls
module for the current release as I initially though, and revisit this
issue later in ORTE
